Our intelligence is physical long before it is anything else. Most of our brain mass exists to co-ordinate the activity of our bodies. Neuroscientists have found that even when you navigate an abstract space—contemplating, say, your company's org chart—you use the same neural machinery you'd use to navigate a real space.
A human hand is capable of moving in twenty-seven separate ways, more by far than any other body part: our wrists rotate, our knuckles move independently of one another, our fingers can spread or contract. The sensors in the skin of the hand are among the densest in the body, and are part of a network of nerves that run along the spinal cord.
